Enterprise class performance The switch features include: · Up to a 16-to-1 reduction in networking cables and connections, concentration of sixteen Gigabit Ethernet server ports down to as little as one Gigabit Ethernet port. This switch has the unique feature to provide both one Gigabit and ten Gigabit ports to the network, allowing the user the ultimate in network flexibility Fully supported on the HP c-Class BladeSystem server blade enclosure and infrastructure compatible with any combination of HP c-Class BladeSystem server blades Ability to replace an existing switch without having to power down the server blades or the server blade enclosure Pre-configured for immediate use with the HP c-Class BladeSystem server blade enclosure System security including SSH, SCP, 255 port-based IEEE 802.1Q tagged VLANs per switch, RADIUS user authentication and authorization, or TACACS+ AAA An extensive list of industry standard protocol support, compatible with widely-used networking components 9K jumbo frames that improve performance by increasing application throughput and decreasing server processor utilization Robust configuration and management from any switch port using the included browser-based and scriptable command line user interfaces. · · · · · · · Introduction 6 · · · · Support for Telnet, SNMP, SCP, FTP, and TFTP file transfer, human read/write configuration file, XModem, and an extensive list of MIB objects further enhance the management capabilities Fully redundant end-to-end architecture maximizing server availability from the network Support for IGMP snooping for multicasting Support for UFD for network path resiliency. It works in conjunction with NIC teaming functionality that is supported on the blade servers. This feature tracks the link state on uplink ports. When an uplink port goes down or is in STP blocking state, this feature will enable the switch to auto disable the downlinks which are connected to the blade server NICs. This enables NIC teaming software to detect link failure on the primary NIC port and fail over to the secondary NIC in the team. As a result, the secondary path is enabled for continued blade server access. When used in conjunction with UFD, NIC teams on the blade server must be configured for switch redundancy. That is, the team will span ports on both Switch 1 and Switch 2.

RMON performs these major functions: o o o Gathers cumulative statistics for Ethernet interfaces Tracks a history of statistics for Ethernet interfaces Creates and triggers alarms for user-defined events · · · · · · · An administrator can define end user accounts that permit limited access to the switch. The switch requires username/password authentication for end users. Fast Uplink Convergence that enables the switch to quickly recover from the failure of the primary link or trunk group in a Layer 2 network using Spanning Tree Protocol. Support for SSH version 2. SSH is a protocol that enables remote administrators to log securely into the switch over a network to execute management commands. Switch software provides SNMP support for access through any network management software, such as HP OpenView. Support for HTTP software upgrade using the BBI. FTP or TFTP server is not required to perform a software upgrade. Port Fast Forwarding that allows a port that participates in Spanning Tree to bypass the Listening and Learning states and enter directly into the Forwarding state. Allows secure browser access (HTTPS) to management functions Switch redundancy In a dual switch configuration, the switches offer several redundancy and failover features. With these features, the network configuration is designed to allow for continued network access to each server blade in case of a component or link failure. The switch redundancy and failover features include: Introduction 7 · · · · · Up to eight separate switches per one HP c-Class BladeSystem server blade enclosure Up to four, one Gigabit Ethernet uplink ports and three, ten Gigabit Ethernet uplink ports (ports 1921), per switch, for designing fully meshed uplink paths to the network backbone Server networking connections routed to each of the separate switches for redundant paths to tolerate a switch or port malfunction Redundant data path ten Gigabit Ethernet cross connection between switches STP support that eliminates potential problems caused by redundant networking paths and provides for failover with a secondary path in case of primary path failure; supports IEEE 802.1D Spanning Tree Protocol and is compatible with Cisco® PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q tagging. The switch also supports IEEE 802.1s MSTP and IEEE 802.1w RSTP. Redundant power supplies and redundant cooling fans within the server blade enclosure Redundant firmware images and configuration settings on switch flash memory Redundant, configurable DNS clients, syslog servers, gateways, and community strings and SNMP trap manager hosts · · · Configuration and management The switch provides these configuration and management interfaces and tools: · · · · · A scriptable CLI allows local, Telnet, or SSH access. An iSCLI that is software selectable. A BBI allows remote access using a Web browser such as Microsoft® Internet Explorer or Netscape Navigator. SNMP manageability and monitoring are supported. The switch functionality allows uploading and downloading of switch configurations through TFTP and SCP, thus allowing the rapid deployment of multiple server blade systems, and providing robust backup and restore capabilities. NTP is supported, allowing the switch to display and record the accurate date and time as provided by an NTP server. Two firmware images, either of which can be selected to be the current runtime image, can be held in memory. RADIUS provides support for user authentication and authorization. TACACS+ provides support for Cisco TACACS+ server compatible authentication, authorization, and accounting. The user interfaces provide multi-level password protected user accounts. IP settings are set manually or obtained automatically from a BOOTP server. A text-based, human read/write configuration file provides viewing, printing, and editing capabilities. A DNS client supports primary and secondary DNS servers. Any port can be enabled or disabled as desired. Any switch port can be used to perform switch management and PXE. · · · · · · · · · · Introduction 8 Diagnostic tools The hardware, software, and firmware diagnostic tools that are available include: · · · · · · · · · · · · · HP Systems Insight Manager automatic discovery and identification POST built into the switch boot process Switch port mirroring Switch LED panel displaying per port status and speed System, management, and option compatibility status LEDs Rear panel reset power switch and DB-9 management serial port Statistic monitoring including port utilization, data packets received/transmitted, port error packets, trunk utilization, and so on Ping and trace route capability Remote syslog with support for primary and secondary syslog server The ability to return the switch to known good condition in case of firmware corruption State information dump for tuning and debugging switch performance Panic command for immediate state dump to flash memory and automatic switch boot Ability to set NVRAM diagnostic flags Switch architecture The HP c-Class BladeSystem provides Ethernet switching technology for network cable reduction. The switch does not affect or determine NIC enumeration and the associated mapping of NIC interfaces to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is determined by the server type, the server operating system, and what NICs are enabled on the server. Port Mapping For detailed port mapping information, see the HP BladeSystem enclosure installation poster or the HP BladeSystem enclosure setup and installation guide on the HP website (http://www.hp.com/go/bladesystem/documentation). Dual switches In a dual switch configuration, two switches in the server blade enclosure provide switch redundancy and redundant paths to the network ports on the server blades. Each switch has four, one Gigabit and three, ten Gigabit external Ethernet ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the enclosure. Redundant crosslinks In a dual switch configuration, the two switches are connected through a single ten gigabit crosslink. This crosslink provides throughput of ten Gb/s for traffic between the switches. Introduction 9 This crosslink is disabled by default. This crosslink must be enabled for use. Redundant paths to server bays In a dual switch configuration, redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. This configuration provides redundant paths to each server bay. Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. However, specific switch port to server mapping varies depending on which type of server blade is installed. On a heavily used system, using a single uplink port for 32 Ethernet signals causes a traffic bottleneck. For optimum performance, HP recommends using at least one uplink port per switch. Supported technologies Layer 2 switching The switch uses Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the OSI model, which is concerned with moving data packets across a network by enforcing CSMA/CD. This layer performs: · · · · · Ethernet packet framing MAC addressing Physical medium transmission error detection Medium allocation (collision avoidance) Contention resolution (collision handling) Layer 2 switching technology allows the switch to look into data packets and redirect them based on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being transmitted to all ports, are transmitted to the destination port only. Layer 3 switching In addition to Layer 2 features, the switch also supports Layer 3 switching. Layer 3 switching features include: · · · · IP forwarding Static routing Dynamic routing based on RIP V1/V2 or OSPF protocols High availability VRRP Layer 3 switching provides more power, flexibility, and security capabilities to network administrators. Network traffic is managed much more efficiently and broadcast traffic between servers remains within the enclosure. Security features provide added protection for switch configuration data, while packet filtering helps secure and segment sensitive traffic or network access. Introduction 10 IEEE 802.1 Q-based VLAN The switch provides support for a total of 1000 IEEE 802.1Q VLANs for server grouping and isolation. A VLAN is a network segment configured according to a logical scheme rather than a physical layout. VLANs are used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN. VLANs also logically segment the physical network into different broadcast domains so that packets are forwarded only between ports within the VLAN. This technology enhances performance by conserving bandwidth and improves security by limiting traffic to specific domains. For example, isolate the server blade iLO ports from the rest of the NICs. The iLO ports on Switch 2 are assigned to their own VLAN and go to a dedicated uplink or share an uplink using VLAN tagging. IMPORTANT: The greater the number of VLANs, the greater the switch CPU utilization. For maximum switch performance, HP recommends being judicious when configuring the number of VLANs. NOTE: VLAN 4095 is reserved for future functionality. Spanning Tree Protocol The switch supports IEEE 802.1D STP, which allows the blocking of links that form loops between switches in a network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link is activated. In addition, the switch provides a spanning tree domain per VLAN. The switch is compatible with Cisco® PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q tagging. Thirty-two spanning tree domains are supported per switch. NOTE: STP 32 is reserved for future functionality. The switch also provides IEEE 802.1s-based MSTP and IEEE 802.1w-based RSTP. SNMP The switch is configured and monitored remotely from an SNMP-based network management station. The switch supports industry-standard SNMP MIBs and proprietary HP enterprise switch MIBs for fault detection and monitoring of switch functionality. In addition, the switch supports various environmental traps such as temperature and fan failure traps. To secure the management interface, the switch administrator configures community strings with two levels of access: Read and Read/Write. Access to the switch is also restricted to only management stations that are members of a specific IP network. This is achieved by configuring the address/mask of that specific network as a restricted management network address/mask. Introduction 11 Port mirroring The switch allows mirroring of one or multiple ports (source ports) to another port (destination port) for network monitoring and troubleshooting purposes. This technology offers a way for network packet analyzers to view the traffic moving through the switch by providing a copy of the traffic that is currently being passed through any other port. The packets are sent to a network packet analyzer or other monitoring device attached to the mirror port. Port trunking and load balancing The switch supports EtherChannel compatible IEEE 802.3ad (without LACP) port trunking allowing several ports to be grouped together and act as a single logical link called a trunk. This feature provides a bandwidth that is a multiple of the bandwidth of a single link. It also improves reliability since load balancing is automatically applied to the ports in the trunked group. A link failure within the group causes the network traffic to be directed to the remaining links in the group. TFTP support TFTP support allows the switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the switch. Firmware images of the switch are also uploaded to a TFTP server, a configuration file is downloaded into a switch from a TFTP server, and configuration settings are saved to the TFTP server. Store and forward switching scheme The switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily used switch. Packets that cannot be forwarded are saved immediately, rather than dropped, so that packets behind them are less likely to be dropped in periods of heavy usage. BOOTP By default, the switch is configured to obtain an IP address from a BOOTP server during the boot process. The IP settings are also manually configured by means of the serial interface. The IP settings are configurable from the browser-based interface, but because the connection is based on an IP address for these interfaces, users will have to reconnect with the newly assigned IP address. NTP The switch maintains the current date and time. This information displays on the management interfaces and is used to record the date and time of switch events. Current date and time information are manually set on the switch or are obtained through NTP. NTP allows the switch to send a request to a primary NTP server in each polling period asking for GMT. RADIUS The switch supports the RADIUS method to authenticate and authorize remote administrators for managing the switch. This method is based on a client/server model. The RAS, the switch, is a client to the back-end Introduction 12 database server. A remote user (the remote administrator) interacts only with the RAS, not the back-end server and database. RADIUS authentication consists of: · · · A protocol with a frame format that utilizes UDP over IP, based on RFC 2138 and 2866 A centralized server that stores all the user authorization information A client, in this case, the switch The switch, acting as the RADIUS client, communicates to the RADIUS server to authenticate and authorize a remote administrator using the protocol definitions specified in RFC 2138 and 2866. Transactions between the client and the RADIUS server are authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the RADIUS client (the switch) and the back-end RADIUS server. The benefits of using RADIUS are: · · · · Authentication of remote administrators Identification of the administrator using name/password Authorization of remote administrators Determination of the permitted actions and customizing service for individual administrators TACACS+ The switch supports the TACACS+ method to authenticate, authorize, and account for remote administrators managing the switch. This method is based on a client/server model. The switch is a client to the back-end TACACS+ AAA server. A remote user (the remote administrator) interacts only with the client, and not with the back end AAA server. The TACACS+ AAA method consists of: · · · A protocol with a frame format that utilizes TCP over IP A centralized AAA server that stores all the user authentication, authorization, and accounting (of usage) information A NAS or client (in this case, the switch) The switch, acting as the TACACS+ client or NAS, communicates to the TACACS+ server to authenticate, authorize, and account for user access. Transactions between the client and the TACACS+ server are authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+ server. The switch supports: · · · Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not supported. One-time password authentication is also not supported. Authorization privilege levels of only 0, 3, and 6. These map to management levels of user, oper, and admin, respectively. The accounting attributes of protocol, start_time, stop_time, and elapsed_time. For BBI users, accounting stop records are only sent if the user presses the QUIT button. Introduction 13 SSH and SCP SSH and SCP use secure tunnels to encrypt and secure messages between a remote administrator and the switch. Telnet does not provide this level of security. The Telnet method of managing a switch does not provide a secure connection. SSH is a protocol that enables remote administrators to log securely into the switch over a network to execute management commands. SCP is used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the network. On a switch, SCP is used to download and upload the switch configuration via secure channels. XModem The switch supports XModem for transferring files during direct dial-up communications. XModem sends blocks of data in 128-byte blocks, and includes an error-detection system called a checksum. When the data is received, the error detection system ensures that the entire message reached its destination. If not, the receiving computer sends a request for retransmission of the data. IGMP Snooping The switch supports IGMP Snooping for multicasting. Version 1-, Version 2-, and Version 3-based IGMP Snooping are supported. In addition, auto detection of the multicast router port and manual configuration of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering option is supported. Jumbo frames By default, the switch supports jumbo frames up to 9216 bytes, which help reduce server CPU utilization and increase application throughput. No configuration is required. The switch does not fragment frames as they exit, or assemble packets into jumbo frames as they enter the switch. Auto-MDI/MDIX The switch RJ-45 Ethernet ports are MDI/MDI crossover capable. MDI/MDIX is a type of Ethernet port connection using twisted pair cabling. The MDI is the component of the MAU that provides the physical and electrical connection to the cabling medium. An MDIX is a version of MDI that enables connection between like devices. MDI ports connect to MDIX ports via straight-through twisted pair cabling whereas both MDI-to-MDI and MDIX-to-MDIX connections use crossover twisted pair cabling. The switch has the capability to automatically detect the cable selection/type, making the distinction between a straightthrough cable and a crossover cable unimportant. Auto-negotiation of duplex mode and speed on 1 Gigabit ports Auto-negotiation of duplex mode and speed are configured on the switch. Network adapters that support multiple data speeds, such as Fast Ethernet and Gigabit Ethernet, choose the speed at which they run through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier. Introduction 14 Redundant images in firmware The switch stores up to two different software images, called image1 and image2, as well as boot software, called boot. When downloading new software, the ability to specify where it is to be placed (into image1, image2, or boot) is activated. For example, if the active image is currently loaded into image1, load the new image software into image2. This allows a test of the new software and the option to revert back to the original image stored in image1, if needed. CAUTION: Unlike the firmware that has two images, there is only one image of boot supported. Upgrading the boot image replaces the original boot image.

This address is needed when configuring the switch. Planning the switch configuration The switch ships with a default configuration in which all downlink and uplink ports are enabled and assigned a default VLAN with a VID equal to 1. This default configuration simplifies the initial setup by allowing use of a single uplink cable (from any external Ethernet connector) to connect the server blade enclosure to the network. Assess the particular server environment to determine any requirements for other considerations. The switch does not affect or determine NIC numeration and the associated mapping of NIC interfaces to switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is determined by the server type, the server operating system, and which NICs are enabled on the server. NOTE: Port 18 is reserved for connection to the Onboard Administrator module for switch management. This allows a user to enable the functionality of future firmware upgrade releases. The Onboard Administrator module controls all port enabling. Enabling is based on matching ports between the server and the interconnect bay. Before power up, the Onboard Administrator module verifies that the server NIC option matches the switch bay that is selected and enables all ports for the NICs installed. For detailed port mapping information, see the HP BladeSystem enclosure installation poster or the HP BladeSystem enclosure setup and installation guide on the HP website (http://www.hp.com/go/bladesystem/documentation). Default settings When planning the configuration, consider the default settings for these parameters: · · · · · · Switch IP settings VLAN settings XFP settings Port names and types Port trunking settings Interswitch X-Connect port settings Installing the switch 18 · · · · SNMP settings User name and password settings Default access to various management interfaces NTP settings IMPORTANT: See "Runtime switching software default settings (on page 32)" for a complete list of default configuration settings. Switch security When planning the switch configuration, secure access to the management interface by: · · · Creating users with various access levels Enabling or disabling access to various management interfaces to fit the security policy Changing default SNMP community strings for read-only and read-write access User, operator, and administrator access rights To enable better switch management and user accountability, three levels or classes of user access have been implemented on the switch. Levels of access to CLI, Web management functions, and screens increase as needed to perform various switch management tasks. Conceptually, access classes are defined as: · User interaction with the switch is completely passive. Nothing can be changed on the switch. Users can display information that has no security or privacy implications, such as switch statistics and current operational state information. Operators can only effect temporary changes on the switch. These changes will be lost when the switch is rebooted/reset. Operators have access to the switch management features used for daily switch operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot severely impact switch operation. Administrators are the only ones that can make permanent changes to the switch configuration, changes that are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and troubleshoot problems on the switch. Because administrators can also make temporary (operator-level) changes as well, they must be aware of the interactions between temporary and permanent changes. · · Access to switch functions is controlled through the use of unique user names and passwords. Once connected to the switch via the local console, Telnet, or SSH, a password prompt appears. NOTE: It is recommended to change the default switch passwords after initial configuration and as regularly as required under the network security policies. For more information, see the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide. The default user name and password for each access level are: Installing the switch 19 User account User Description and tasks performed Password The user has no direct responsibility for switch management. He or she user can view all switch status information and statistics, but cannot make any configuration changes to the switch. Operator The operator manages all functions of the switch. The operator can reset ports or the entire switch. By default, the operator account is disabled and has no password. The super user administrator has complete access to all menus, information, and configuration commands on the switch, including the ability to change both the user and administrator passwords. admin Administrator Manually configuring a switch The switch is configured manually using a command line interface, a browser-based interface, or an SNMP interface. See the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide for more information on using these management interfaces to configure the switch. After a switch is configured, back up the configuration as a text file to a TFTP server. The backup configuration file is then downloaded from the TFTP server to restore the switch back to the original configuration. This restoration is necessary if one of these conditions apply: · · The switch configuration becomes corrupted during operation. The switch must be replaced because of a hardware failure. Configuring multiple switches Configure multiple switches by using scripted CLI commands through Telnet or by downloading a configuration file using a TFTP server. Using scripted CLI commands through Telnet The CLI, provided with the switch, executes customized configuration scripts on multiple switches. A configuration script is tailored to one of the multiple switches, and then that configuration can be deployed to other switches from a central deployment server. Using a configuration file If planning for the base configuration of multiple switches in a network to be the same, manually configure one switch, upload the configuration to a TFTP server, and use that configuration as a base configuration template file. Switch IP addresses are acquired by default using BOOTP, therefore, each switch has a unique IP address. Each switch is remotely accessed from a central deployment server and an individual switch configuration is downloaded to meet specific network requirements. See the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide for additional information on using a TFTP server to upload and download configuration files. Installing the switch 20 Installing the switch CAUTION: Do not cable the switch until after configuration. IMPORTANT: Make sure that the server NIC configuration matches the switch bay selected. NOTE: When installing two switches, there is one switch interconnect port between adjacent I/O bays. Port 17 is disabled by default. The port must be manually enabled to use. A successful installation is indicated by a green Health LED. If the Health LED is amber or power is not applied to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and installation guide for more information. Installing the switch 21 Accessing the switch The switch is accessed remotely using the Ethernet ports or locally using the DB-9 management serial port. To access the switch remotely: 1. 2. 3. Assign an IP address. By default, the switch is set up to obtain its IP address from a BOOTP server existing on the attached network. From the BOOTP server, use the switch MAC address to obtain the switch IP address. From a computer connected to the same network, use the IP address to access the switch using a Web browser or telnet application, which enables access to the switch BBI or CLI. The switch logon prompt appears. NOTE: If the switch does not obtain the IP address by means of the BOOTP service, access the switch locally and configure the IP address manually. After assigning the IP address to the switch, then access the switch remotely. To access the switch locally: 1. 2. Connect the switch DB-9 serial connector, using a null-modem serial cable to a local client device (such as a laptop computer) with VT100 terminal emulation software. Open a VT100 terminal emulation session with these settings: 9600 baud rate, eight data bits, no parity, one stop bit, and no flow control. Logging on and configuring the switch To log on to the switch: 1. Access the switch ("Accessing the switch" on page 22). After connecting to the switch console, the login prompt appears. 2. Enter admin as the default administrator password. The Main Menu appears and displays all administrator privileges: See the HP 1:10Gb Ethernet Blade Switch for c-Class BladeSystem Command Reference Guide for information on configuring the IP address, changing configuration settings, and monitoring switch operation using one of the following interfaces: Installing the switch 22 · · Local RS-232 serial console management interface Remote telnet console management interface See the HP 1:10Gb Ethernet Blade Switch for c-Class BladeSystem Browser-based Interface Reference Guide for information on using the embedded HTML interface to manage the switch from anywhere on the network using a standard browser, such as Netscape Navigator or Microsoft® Internet Explorer. See "SNMP MIBs support (on page 47)" for more information on the SNMP agents. This section also describes how to use the MIBs to configure and monitor the switch using a generic SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager. Installing XFP transceivers CAUTION: To prevent damage to the fiber optic cable or the XFP transceiver, do not install or remove fiber-optic XFP transceivers with cables attached. Disconnect all cables from the XFP transceiver before removing or installing an XFP transceiver. CAUTION: Removing and installing an XFP transceiver can shorten the useful life. Do not remove and insert XFP transceivers more often than is necessary. CAUTION: HP recommends attaching an ESD-preventative wrist strap to your wrist and to a bare metal surface on the chassis to prevent electrostatic discharge. CAUTION: Do not remove the dust plugs from the fiber-optic XFP transceiver or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the XFP transceiver ports and cables from contamination and ambient light. 1. Remove the dust plug and save for future use. IMPORTANT: Use only XFP transceivers purchased from HP. 2. Insert the XFP transceiver. With latch closed, be sure that the transceiver is fully seated and securely in place.

Installing the switch 24 Replacing a switch Replacing an existing switch CAUTION: Removing the switch from a powered enclosure results in the loss of network communications between the server blade network ports that are connected through this switch and the segment of network infrastructure those ports need to communicate. For continued blade server network communication and services availability before removing the switch, redirect critical high-availability services or applications to use the redundant network ports available on those blade servers that are connected through the redundant switch in the enclosure. CAUTION: Do not cable the switch until after configuration. To replace an existing switch: 1. Save the configuration file to a TFTP server for later retrieval. For more information on saving a configuration file to a TFTP server, see the HP 1:10Gb Ethernet BL-c Switch Command Reference Guide. Remove and label the cables. Remove the switch. 2. 3. 4. 5. Slide the new switch fully into the interconnect bay. For more installation information, see "Installing the switch (on page 21)." Close the ejector lever and wait for the switch boot up completely.

download of the switch operating system firmware, or boot code firmware if upgrading a switch directly from any existing OS or boot code images. This procedure requires: · · · A computer running terminal emulation software A standard null modem cable with a female DB-9 connector A switch OS firmware and/or boot code images Serial upgrade of boot code firmware image procedure To perform a serial upgrade of the switch boot code firmware image, usually named GbE2c-110G_b_100.bin: 1. 2. Using the null modem, connect the console port of the switch to the serial port of a PC that supports XModem/1K XModem. Start HyperTerminal (part of Microsoft Windows) or equivalent terminal emulation application (depending on the computer operating system), and set the parameters for the terminal emulation console: Value 9600 8 None 1 None Parameter Baud rate Date bits Parity Stop bits Flow control 3. Power on the switch. Performing a serial download 41 4. Hold down the Shift key and press the D key repeatedly during the Memory Test, until this message appears: NOTE: To perform serial downloads at 57600 baud rate, press the Shift-F keys. To perform serial downloads at 115200 baud rate, press the Shift-D keys. 5. After the message in Step 4 appears, reconfigure the terminal emulation console using these parameters. Value 115200 8 None 1 None Parameter Baud rate Data bits Parity Stop bits Flow control 6. Press the Enter key several times on the PC that is connected to the console port of the switch. When the console port is successfully communicating with the PC, indicating readiness for image transfer, continuous C's appear: 7. Be sure that the new switch boot code firmware file is available on the computer. This file can be downloaded from the CD that is shipped with the switch or from the HP website (http://www.hp.com/go/bladesystem/documentation). Performing a serial download 42 8. Select from the menu and choose these options in the Send File window: The Send File window displays progress of the file transfer. The file transfer might take up to seven minutes. NOTE: Although slower, XModem also works if 1K MODEM is not used. 9. After completing the transfer, a message displays how many bytes transferred, followed by another message displaying the status of image extraction. Do not power cycle the switch during this process. After extracting the image, it is updated to flash and a message with a progress indicator displays as shown. CAUTION: Do not power off the switch until the message: "Change your baud rate to 9600 bps and power cycle the switch," is displayed, otherwise, the switch will be inoperable. 10. Change the baud rate to 9600 and power off the switch, wait for a few seconds, and power on the switch. The switch boots with the new version of the boot code image that was just downloaded.
